Hi-Speed

"Where did the note go!?" - Hi-Speed: How it works and common effects using Hi-Speed.

Quick Overview

Hi-Speed option

Hi-Speeds (soflan) change the speed of notes and the distance between them. They don't change the timings of the notes. You can place the Hi-Speed event by pressing (or 9 by default) in Timeline Tools and place it anywhere.

[Advanced] Calculating the Note Distance between Hi-speeds

• The distance between any two notes is the sums of each hi-speed and their lengths.

  • e.g. A 2/16th measure @ x5, 2/16ths @ x2, and 6/16ths @ x1 would look like a 20/16th distance. (5*2/16 + 2*2/16 + 1*6/16 = 20/16)

• At x0.001, an entire measure (1) would look like a distance of 1/1000th. (0.001*1 measure = 1/1000 measures) This effectively makes the notes stop completely.

  • Inversely, at x1000, a 1/16th would look like a distance of 62.5 measures. (1000*1/16th measure = 62.5 measures) This effectively makes all the notes so fast they're invisible.

Negative Hi-Speeds

Hi-Speeds value can also go below x0. Instead of going towards the judgement line, notes will go backwards.

• A x-1000 and a x1000 of equal lengths will not cancel out to a x1 distance; it will cancel out to a x0. (-1000 + 1000 = 0 measures)

  • A x1 distance is made with a x1000 and x-998. (1000*1/2 measures + -998*1/2 measures = 2*1/2 = 1 measure)

Common Effects

Notes Come from the Bottom and Fall Down

1. Place 3 Hi-Speeds:

   1. x10000 (or higher) before the last two Hi-Speeds (to teleport the note to under the judgement line)

   2. A negative value Hi-Speed.

   3. A positive value Hi-Speed.

Step 1

1. Interpolate Hi-Speeds between the last 2 Hi-Speeds. (This step can be done easily in MMW4CC like so.)

Different Hi-Speeds in Different Notes (MMW4CC)

• Place 2 simultaneous notes, one on a separate timeline with a different speed (called "Layers" in MMW4CC).

Notes Suddenly Turns Invisible

[For Beginners] Place a x-9999 Hi-speed on each note you want to make disappear, and a x10000 Hi-Speed halfway between each note. Do this for every other notes (remember to add separate Layers per notes for this effect). [Advanced] Original: lawneater (message link)

1. Place a x1000 on the point where you want your notes to go invisible, and on each note during that time. (You can stop after about half a measure.)

2. Take note of your division. The smaller the better. Try to use a number that is divisible by the division your notes are on.

   • (e.g notes are on 16ths -> use 1600 division; notes on 24ths - > use 1200 division)

3. Place a Hi-speed 1 step after the x1000 Hi-speed.

4. Set value for the Hi-speed to (d*n - 1000)/(d*n -1)

   • where d is your division

   • and n is the reciprocal of the distance between this x1000 and the next x1000 Hi-speed in measures (e.g. 1/16, 17/24)

5. Repeat Steps 3 and 4 for each note. Your chart should look something like this.
